My research focus has been to support knowledge sharing. I use this term broadly, and associated research questions cover issues such as knowledge representation, ontology alignment, and interoperation of on-line resources, and even human-human communication in support of knowledge sharing. I have research interests in areas such as:

My current research focuses on knowledge based systems that help with knowledge sharing. This broad goal can be applied in a variety of ways to a variety of BHI domains. Here is a list of current projects; for past projects, see my publication list.

With Professor Mark Phillips of Radiation Oncology, I co-lead an "Informatics in Radiation Oncology and Knowledge representation" (IROK) research group. We are currently exploring two (very) different research directions. One is to apply Bayes Nets to assess the quality of radiation treatment plans, based on prior knowledge of "good" plans, and then to explore an "Ontology" approach to construction of such Bayes' nets. The other direction is to elicit patient symptoms to better track progression and enable quality follow-up decisions after radiation treatment for brain cancers and brain metastases.
